Is that one EFI per OS, or multiple identical EFI? :-)

Neither. Multiple possibly not identical EFI partitions

how is that related to RAID at all?

RAID provides redundancy while the system is running 

RAID provides redundancy for devices - no matter if something is running

For boot 
redundancy, the boot loader must be installed on each disk

so what

With EFI 
boot, it means there must be an EFI partition on each disk. But EFI 
partitions do not need to be identical as long as any of them can boot 
the system

so what - the topic is "Transferring an existing system from non-RAID 
disks to RAID1 disks in the same computer"

anything else for the sake of god belongs to a different topic

the same as for "What does TRIM/discard in RAID do" which is a question 
about the state of play

would you be so kind and stop mixing completly different topics in the 
same thread - that way people who don't give a shit about several topics 
they can simply ignore them
